To all 'whom it may concern:

Be it known that l, Emmnsr T. VELCOME, a citizen of the United States,residing in the city of New York, county of New York, and State of NewYork, have invented an Improved Sewage-Disposal System, of which thefollowing is a specification.

rlhis invention is a sewage disposal system wherein the liquid,semi-solid and solid foreign matter in the sewage are separated, theliquid passed' to a filter', the semi-solid matter passed to a storagereservoir having a furnace connected therewith, the solid foreignmattei' passed to a receiving chamber connected with the furnace, andthe gases recovered or burned.

rl`he leading objects are the recovery of the constituents of sewagevaluable in the arts, primarily as fertilizers, the purifica- .y tion ofcontaminated water and the destruction of offensive odors.

lhe accompanying drawing shows a sectional elevationof apparatusembodying my invention.

The invention, as shown in the drawing, comprises the flume 1,controlled by a valve 2, and discharging into a revoluble coarse screen3 inclosed by and fixed to a revoluble fine screen 4 disposed within astationary casing 5. The upper ends of the screens 3 and 4 are connectedby a collar 6 which revolves on rollers 7, the collar revolving aroundthe outlet end 1f of the flume 1 and within the closed upper end 5L ofthe casing 5. The lower ends of the screens 3 and 4 are connectedtogether by a spider 6 which revolves within the closed lower end 5b ofthe casing o and has thereon theI circular rack 8 engaged by the drivinggear 9, by means of which the screens are revolved.

rEhe casing 5 discharges, by way of a hop- `per or funnel 5c in thebottom thereof, into a conduit 10, controlled by a valve 10a, whichdischarges into a filter 11 accessible in any suitable maner, as by amanhole 11a.

The interior of the screen 4 discharges through its open lower end intothe conduit 12 and thence into a reservoir 13, the latter having thebottom hoppers 13a, controlled by valves 13b, placed above the tracks 14by which cars 15 are passed under the hoppers and loaded with thecontents of the reservoir.

The screen 3 has the extension 3a thereon which discharges into areceiving chamber 1G having the neck 1G in which the part 32 revolves, avalve 16D Acontrolling the discharge from the screen 3 to the chamber16.

A furnace 17 has a door or passage 17a connecting its primary combustionchamber 17D with the chamber 16 so that refuse matter collected anddried in this chamber can be passed into the combustion chamber andconsumed.

A cupola or stack 18, above the reservoir 13, communicates, by thepassage 18, with the furnace combustion chamber, and in the y passagethrough the cupola or stack are placed removable trays 18'J loaded withchlorid of lime or other suitable material for absorbing gases given offby the matter contained in the reservoir. A blower 19, having a nozzle19a, forces a stream of air through the passage 18a to draw off thegases from the reservoir through the absorbent material and carry theunabsorbed gases into the furnace.

It will be understood that, in operation, the sewage, discharged by thefiume 1 into the revolving coarse 'screen 3, is separated thereby: thesolid foreign matter, such as large pieces of paper, sticks and thelike, passes through the extension 3a into the chamber 16, while theliquid and semi-solid matter passes through the coarse meshes of thescreen, upon the interior of the cylindrical body of the finer meshscreen 4. The screen 4 passes the liquid through its meshes into thecasing 5, whence it flows by the conduit 10 into the filter 11, and thelsemi-solid matter is delivered through the open lower end of the screen4, whence it flows by the conduit 12 into the reservoir 13. The liquid,which is passed through the filter 11, is so cleansed thereby that itcan be turned into streams without contaminating the waters thereof,while the filter collects, particularly upon the upper strata thereof,matter having valuable fertilizing properties, which can be removedperiodically. The semi-solid mat ter (chiefly excrement) which iscollected in the reservoir 13, is carried away therefrom, by cars 15, tobe treated as provided in my Patent No. 889,418, or otherwise. Thematerial used in the trays, for absorbing the chemical constituents ofthe gases passed ofi' from the reservoir, can be changed from time totime, the saturated material being used either as a fertilizer directlyor its constituents may be driven off and collected. Gases passingthrough the trays and the solid matter dried in the chamber 16 are con-Y sumed in the furnace.
